numerically instability

[goodman249]

When I run FDS, the simulation becomes a2_b_3.out.txt after reaching halfway through the simulated time. The FDS version is 6.7.4. Could you check if any additional code needs to be added to allow the simulation to continue? This would be very helpful for me. The model involves a significant increase in wind speed, and I'm not sure if this is the cause of the numerical instability.Thank you.

Hello, is there a specific reason you're using an old version of FDS? In the meantime, while someone finds time to help, you might want to try the current version.
